Hi all
I have an abacus 6p led display in my unit.
It's around 20 years old and never had a problem.
Following a massive power cut it is coming up with error zone 6b.
The issue is I don't have a 6b. I have a zone 6 (360 dtec) but not a 6b.
The system is regularly maintained and has never had an issue.
Any ideas what 6b is?
